DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figures 1-6 The LED display monitoring and control device shown in the figure includes an LED display body 101. A mounting box 102 is provided on the back of the LED display body 101. A control card board 103 is provided in the mounting box 102. The control card board 103 is of model CR2032. The device also includes four mounting tubes 2 provided on the inner wall of the mounting box 102 on a side close to the LED display body 101. The four mounting tubes 2 are provided with a fixing assembly for fixing the LED display body 101 and a buffer assembly for buffering the vibration of the LED display body 101 during use.

[0025] The buffer assembly includes a buffer plate 301 slidably connected to the mounting tube 2. A buffer rod 302 is fixedly connected to one side of the buffer plate 301 close to the LED display screen body 101. A first spring 303 is fixedly connected to the other side of the buffer plate 301. The other end of the first spring 303 is connected to the bottom wall of the mounting tube 2. The mounting tube 2 is provided with a damping assembly for damping the LED display screen body 101.

[0026] It should be noted here that the control card board 103 is installed and fixed using a fixing component, thereby ensuring the firmness of the installation of the control card board 103. At the same time, the buffer component and the damping component provide the control card board 103 with two layers of buffer protection, thereby reducing the vibration amplitude of the control card board 103, further improving the connection stability of the control card board 103 when used in a vibration environment, thereby ensuring the continuity of signal transmission and monitoring of the LED display screen body 101 by the control card board 103.

[0027] It's important to note that LED display monitoring and control devices specifically refer to a combination of devices used to monitor and control the operating status of LED displays. These devices typically consist of both hardware and software components, working together to ensure the performance, stability, and safety of the LED display. The hardware primarily includes a control card (also known as a transmitter card), a power controller, a temperature sensor, a brightness adjuster, and an alarm device. The software primarily includes display control software and monitoring and management software.

[0028] See also Figure 4 The damping assembly shown in the figure includes two symmetrically arranged U-shaped tubes 401 fixedly connected to the side wall of the mounting tube 2. A plurality of damping plates 402 are staggeredly arranged on the inner walls of the two U-shaped tubes 401. The mounting tube 2 is filled with damping fluid.

[0029] It should be noted here that: by setting the damping component, a damping mechanism is formed, which provides a resistance buffering effect for the control card board 103, and further provides a second layer of buffering effect for the control card board 103.

[0030] Working principle: When the LED display screen body 101 is in use, the control card board 103 is first installed in the installation box 102 using a fixing assembly, so that the control card board 103 can convert images, text and other information in the computer into signals that can be recognized by the LED display screen body 101 and send them to the LED display screen body 101 for display. At the same time, it can also detect the working status of the LED display screen body 101. The detection of the LED display screen body 101 is achieved by the cooperation of multiple components, mainly including hardware and software. The control card board 103 is only one of the components for detecting the LED display screen body 101.

[0031] During the use of the LED display screen body 101, if the LED display screen body 101 is in a vibrating environment or a speaker is installed near the LED display screen body 101, the control card board 103 will be affected by the vibration. When the control card board 103 is vibrated, the buffer plate 301 will be driven to move in the installation tube 2 through the buffer rod 302. As a result, during the movement of the buffer plate 301, the first spring 303 is compressed or stretched, causing the first spring 303 to deform under stress and generate elastic force. Therefore, under the elastic action of the first spring 303, a first layer of buffer protection is provided for the control card board 103.

[0032] At the same time, during the movement of the buffer plate 301 in the mounting tube 2, the damping liquid in the mounting tube 2 will be compressed, so that the damping liquid will flow from the U-shaped tube 401 on the side wall of the mounting tube 2, and the multiple damping plates 402 in the U-shaped tube 401 will exert resistance to the flow of the damping liquid, thereby forming a damping mechanism, providing a resistance buffering effect for the control card board 103, and further providing a second layer of buffering effect for the control card board 103. Through the two layers of buffering effect, two layers of buffering protection are provided for the vibration experienced by the control card board 103, thereby reducing the vibration amplitude experienced by the control card board 103, and further improving the connection stability of the control card board 103 when used in a vibration environment, thereby ensuring the continuity of signal transmission and monitoring of the LED display screen body 101 by the control card board 103.

[0033] Example 2

[0034] See also Figure 3 and Figure 4 This embodiment further explains Example 1. The fixing assembly shown in the figure includes a fixing cavity 501 formed in the buffer rod 302. A plurality of through holes 502 are formed in the side wall of the fixing cavity 501. A fixing plate 503 is slidably connected to each through hole 502. The fixing cavity 501 is provided with a driving assembly for driving each fixing plate 503. A fixing ring 504 is fixedly connected to the side wall of the buffer rod 302. The LED display screen body 101 is provided with four fixing holes 505, which are matched with the buffer rod 302.

[0035] It should be noted here that the provision of the fixing assembly facilitates the installation and fixing of the control card board 103 .

[0036] See also Figure 5 and Figure 6 , the driving assembly shown in the figure includes a threaded rod 601 rotatably connected to the bottom wall of the fixed cavity 501, and a driving ring 602 is threadedly connected to the side wall of the threaded rod 601. The fixed cavity 501 is provided with a guide assembly for guiding the movement of the driving ring 602. The driving ring 602 is fixedly connected to two symmetrically arranged connecting plates 604 on one side close to the fixed plate 503. A rotating plate 606 is connected between the two connecting plates 604 through a connecting shaft 605. One end of the rotating plate 606 is connected to the fixed plate 503, and one end of the connecting shaft 605 is fixedly connected to a first baffle 607. The two connecting plates 604 are fixedly connected to a second baffle 608 on one side close to the first baffle 607. The connecting shaft 605 is provided with a pull-back assembly for pulling back the fixed plate 503. The end of the threaded rod 601 away from the mounting tube 2 is arranged through the fixed cavity 501 and is fixedly connected to the driving handle 603.

[0037] It should be noted here that the drive assembly is provided to facilitate the movement of each fixing plate 503 up and down.

[0038] See also Figure 5 The pull-back assembly shown in the figure includes a pull-back plate 701 provided at one end of the connecting shaft 605 away from the first baffle 607, a torsion spring 702 is sleeved on the side wall of the connecting shaft 605, and the two ends of the torsion spring 702 are respectively connected to the pull-back plate 701 and the connecting plate 604;

[0039] It should be noted that, through the arrangement of the rebound assembly, when each fixing plate 503 is engaged with the through hole 502 , the elastic action of the torsion spring 702 will push each fixing plate 503 to rotate away from each other.

[0040] See also Figure 5 The guide assembly shown in the figure includes two symmetrical guide grooves 801 provided on the inner wall of the fixed cavity 501. The two guide grooves 801 are slidably connected to guide plates 802. The opposite ends of the two guide plates 802 are connected to the drive ring 602.

[0041] It should be noted here that the setting of the guide component provides guidance and limiting functions for the movement of the drive ring 602.

[0042] Working principle: When fixing the control card plate 103, first, the fixing hole 505 on the control card plate 103 is aligned with the buffer rod 302, and one side of the fixing hole 505 is abutted against the fixing ring 504 on the side wall of the buffer rod 302. Then, by rotating the driving handle 603, the threaded rod 601 is driven to rotate. Under the transmission effect of the threaded engagement between the threaded rod 601 and the driving ring 602 and the guidance of the guide assembly, the driving ring 602 is driven to move closer to the control card plate 103. When the driving ring 602 moves closer to the control card plate 103, it will synchronously drive the various fixing plates 503 to move.

[0043] When each fixing plate 503 is matched with the through hole 502, the elastic action of the rebound component will drive each fixing plate 503 to rotate away from each other. At the same time, under the blocking action of the first baffle 607 and the second baffle 608, each fixing plate 503 is rotated to a horizontal state. Therefore, as the driving ring 602 continuously approaches the control card board 103, it will push each fixing plate 503 against the side wall of the control card board 103, thereby utilizing the tightening action of each fixing plate 503 to achieve the installation and fixation of the control card board 103.

[0044] When the control card board 103 needs to be disassembled, the driving handle 603 is rotated to drive the driving ring 602 to move away from the control card board 103, and further drive each fixed plate 503 to move away from the control card board 103. When each fixed plate 503 is against the side wall of the through hole 502, under the pressing force, each fixed plate 503 will be driven to rotate. As the driving ring 602 continues to move, each fixed plate 503 will be driven to shrink into the fixed cavity 501, thereby releasing the limit on the control card board 103 and facilitating the disassembly of the control card board 103.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
